<dtml-if w> does what it should do
If "what it should do" means "testing the existence *and* truth of w".
If w is *any* non-False value such as 1, 2, 'hello world', or ['a','b','c'] this test will evaluate True. If w is 0, [], None, or doesn't exist, it will evaluate False. If those results are what you want, cool.
but what you suggest does not work nor do any of the other combinations i have tried. I can demostrate that w=1 by displaying <dtml-var w>.
Or maybe what you've demonstrated is that w is equal to '1', which is going to render the same on-screen but is not the same data. If w is a variable you're grabbing from a form, that's the case almost for certain.
You're far better off writing your tests for the *exact* condition you're testing, rather than using a broad existence/truth test and assuming the rest. If the test "w==1" does not return True, then w is not equal to 1. Maybe it's equal to something that looks like 1, but this is not the same thing.
HTH,
Dylan Thanks for all your help, it is great to feel un-isolated! I have inspected the Request object and the 1 is indeed a '1' so now it works. best regards garry
